Description

When sending data to the stanbol enhancer, I get the attached exception on my console. I use the full launcher with the Zemanta and OpenCalais engines.
Though I retrieve annotations I think the exception should at least be catched and replaced by an appropriate message. This can look "scary" for first-time users.

The command I execute:
curl -X POST -H "Accept: application/rdf+json" -H "Content-type: text/plain" --data "The Eiffel Tower." http://localhost:8080/engines
